The invention provides a battery heating circuit and a control method thereof, a battery and an electric vehicle, the battery comprises a first battery pack and a second battery pack, and the battery heating circuit comprises a switch module, a heating module and a control module. The switch module is connected with the first battery pack and the second battery pack. The heating module is connected with the first battery pack, the second battery pack and the switch module. The control module is connected with the switch module and the heating module, and the control module is used for controlling the switch module to switch the battery to a heating state and controlling the heating module to enable the first battery pack, the heating module and the second battery pack to form a loop when the battery is in the heating state. Wherein the loop is used for transferring electric quantity between the first battery pack and the second battery pack so as to heat the first battery pack and the second battery pack. Through the mode, the heating rate of the battery can be improved.

    本申请提供一种电池加热电路及其控制方法、电池与电动车辆,其中,电池包括第一电池组与第二电池组,电池加热电路包括开关模块、加热模块与控制模块。开关模块分别与第一电池组以及第二电池组连接。加热模块分别与第一电池组、第二电池组以及开关模块连接。控制模块与开关模块以及加热模块连接,控制模块用于控制开关模块,以使电池切换至加热状态,并用于在电池处于加热状态时,控制加热模块,以使第一电池组、加热模块及第二电池组形成回路。其中,该回路用于在第一电池组与第二电池组之间转移电量,以对第一电池组与第二电池组进行加热。通过上述方式,能够提高电池的加热速率。
